所以我使用@Factory用5个不同的电子邮件运行一个测试，但我得到错误的参数数量异常，我无法在控制台上看到完整的错误跟踪。我使用TestNG。这是我的代码：
package com.task.lab.facadetask;
public class GmailTest {
private WebDriver driver;
private static List<User> usersList;
static List<TestMessage> mess;
public GmailTest(){}
@Factory(dataProviderClass = GmailTest.class, dataProvider = "getData")
public GmailTest(WebDriver driver,List<User> usersList, List<TestMessage> mess ){
this.driver = driver;
GmailTest.usersList = usersList;
GmailTest.mess = mess;
}
@BeforeMethod
public void setUpDriver(){
driver = DriverObject.getDriver();
}
@DataProvider
public static Object[][] getData() {
File usersXml = new File("src\\\\main\\\\java\\\\com\\\\task\\\\lab\\\\facadetask\\\\testdata\\\\users.xml");
try {
usersList = JAXB.unmarshal(usersXml);
} catch (JAXBException e) {
e.printStackTrace();
}
TestMessages messages = UnMarshell.unmarshaller();
assert messages != null;
mess = messages.getTestMessages();
return new Object[][]{
{mess.get(0), usersList.get(0)},
{mess.get(1), usersList.get(1)},
{mess.get(2), usersList.get(2)},
};
}
@Test
public void testGmail(TestMessage message, User users) {
String gmailURL = "https://accounts.google.com/signin";
driver.get(gmailURL);
Login loginPage = new Login();
loginPage.login(users.getEmail(), users.getPassword());
GmailMessage gmailPage = new GmailMessage();
gmailPage.sendMessage(message.getReceiver(), message.getSubject(), message.getMessage());
gmailPage.removeMessage();
Assert.assertTrue(gmailPage.isRemoved());
}
@AfterMethod
public void quitBrowser(){
try{
driver.close();
}finally{
driver.quit();
}
}
}
我的假设是，它可能是由将用户和消息的原始非静态列表更改为静态引起的，但DataProvider方法需要是静态的。有人可以指导我做错什么吗？ UPD：所以，我删除了 @BeforeMethod 并在Krishnan建议的 @DataProvider 中包含了驱动程序，但它给了我同样的错误，错误的参数数量。以下是DataProvider现在开始的内容：
@DataProvider
public static Object[][] getData() {
driver = DriverObject.getDriver();
File usersXml = new File //The rest remains the same
另外，我尝试在BeforeMethod中初始化驱动程序，但在这种情况下，Test没有看到它。它看起来像这样：
@BeforeMethod
public void setUpDriver(){
WebDriver driver = DriverObject.getDriver();
}
也许有人能为我提供一个有效的工厂模拟，所以我可以同时运行5个并行测试？我愿意接受建议。
答案 0 :(得分：1)
您的工厂方法被定义为接受3个参数。
@Factory(dataProviderClass = GmailTest.class, dataProvider = "getData")
public GmailTest(WebDriver driver,List<User> usersList, List<TestMessage> mess ){
this.driver = driver;
GmailTest.usersList = usersList;
GmailTest.mess = mess;
}
您的数据提供商仅提供2个参数。您的数据提供商不提供WebDriver。
您可以执行以下操作之一：
DriverObject.getDriver()来增强您的数据提供者以包含WebDriver对象，并删除您的@BeforeMethod方法（或）@BeforeMethod初始化类的WebDriver实例。那应该解决你的问题。
编辑：问题已更新。所以也要更新我的答案。
查看问题的更新，答案在高层次上仍然相同。现在还包括一个样本，它解释了答案。
模拟用户类的外观
import java.util.ArrayList;
import java.util.List;
public class User {
private String name;
public User(String name) {
this.name = name;
}
public String getName() {
return name;
}
public static List<User> newUsers(String... names) {
List<User> users = new ArrayList<>();
for (String name : names) {
users.add(new User(name));
}
return users;
}
}
模拟TestMessage类的外观
import java.util.ArrayList;
import java.util.List;
import java.util.UUID;
public class TestMessage {
private String text;
public TestMessage(String text) {
this.text = text;
}
public String getText() {
return text;
}
public static List<TestMessage> newMessages(int howMany) {
List<TestMessage> msgs = new ArrayList<>();
for (int i = 0; i < howMany; i++) {
msgs.add(new TestMessage(UUID.randomUUID().toString()));
}
return msgs;
}
}
以下是测试类的外观
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.AfterClass;

import org.testng.annotations.Factory;
import org.testng.annotations.Test;
import java.util.Collections;
import java.util.List;
public class GmailTest {
private WebDriver driver;
private List<User> users;
private List<TestMessage> testMessages;
@Factory(dataProvider = "getData")
public GmailTest(WebDriver driver, List<User> users, List<TestMessage> testMessages) {
this.driver = driver;
this.users = users;
this.testMessages = testMessages;
}
@Test
public void testMethod() {
Assert.assertNotNull(driver);
Assert.assertNotNull(users);
Assert.assertNotNull(testMessages);
}
@AfterClass
public void cleanupDrivers() {
if (driver != null) {
driver.quit();
}
}
@DataProvider(name = "getData")
public static Object[][] getData() {
List<User> users = User.newUsers("Jack", "Daniel", "John");
int size = users.size();
List<TestMessage> testMessages = TestMessage.newMessages(size);
Object[][] data = new Object[size][1];
for (int i = 0; i < size; i++) {
data[i] = new Object[]{new FirefoxDriver(), Collections.singletonList(users.get(i)),
Collections.singletonList(testMessages.get(0))};
}
return data;
}
}
